Okay, hi. So i bought minecraft last year , and the first 2 days i played it everything was fine ! Until the 3rd day my mc would not load and would freeze my whole pc. I had few settings changed, and it now lets me play it, but my skin/ everyones skin doesnt show up anymore, and they are just alex/steve. The only version my skin shows up is in 1.8 . Im not good at computer stuff, but is there anything i can do to fix it?
